/**
 * A data access object (DAO) providing persistence and search support for SubjectChildCategory entities.
 * Transaction control of the save(), update() and delete() operations 
 can directly support Spring container-managed transactions or they can be augmented	to handle user-managed Spring transactions. 
 Each of these methods provides additional information for how to configure it for the desired type of transaction control.
